National Geographic Kids Readers have been a hit in the beginning reader category, and this book builds upon that success with a new approach–parents and children reading together. With the same combination of careful text, brilliant photographs, and fun approach to high-interest subjects that has proved to be a winning formula with kids, National Geographic Co-readers provide one page of adult read-aloud and one page of kid read-aloud text on each spread, building toward a collaborative reading experience.
